“Do not have jealousy for one
another and do not have hatred for another and do not back-bite others and be
servants of Allah, brothers to one another.”

A society that becomes contaminated with backbiting will
never see agreement and unity and there will never be closeness and love
amongst the people. They will never become a society that has matured in
humanity, such that love and affection will rule over everyone.

Abû Hurayrah
relates that Allah's Messenger (peace be upon him) said: “Whoever believes in
Allah and the Last Day should speak a good word or remain silent. And whoever
believes in Allah and the Last Day should show hospitality to his neighbor. And
whoever believes in Allah and the Last Day should show hospitality to his
guest.” [Sahîh al-BukhârîandSahîh
Muslim]

Abu Huraira reported: The
Prophet, peace and blessings be upon him, said, “He has not
thanked Allah who has not thanked people.”Source: Sunan Abu Dawud 4811

Islam
appreciates not only giving thanks to Allahسبحانه و تعالىbecause
of boons He endows upon us but
also demands us to thankpeople for their favors and kindness. Just like “hamd” is a requirement
of being a slave (to Allah), so too is thanking (tashakkur) a requirement of
being a human. The religion of Islam orders people to praise (hamd) to Allahسبحانه و تعالىand
also to give thanks to (tashakkur) to people who do us favors.

Conclusion:Gratitude’s importance was emphasized by the Prophet Muhammadﷺ when he took the hand of Mu’aadh ibn Jabalرضي الله عنهand said: O Mu’aadh , by
Allah I love you, by Allah love you.” Then he said, “I advise you, O Mu’aadh,
do not fail to say this after every prayer: The Arabic version of this Hadith
is the following. Let’s ensure that we memorize it and recite it after every
prayer.

Allahumma A’inni Ala zikrika wa shukrika wa
husni ibadatika

O Allah!
Assist me in remembering You, in thanking You, and in worshipping You in the
best of manners.Musnad
